TAP-SOCKET.

Specileation of Letters Patent.

Patented J illy 9', 19.12.

Application filed October 13, 1911. Serial No. 654,531.

To all 'Le/0m t may Centern Be it" known that l, hinten NOAH CLoUsr, a Citizen of the United States, re-

siding at in the county of Seneca and State of Ohio, have invented a new and uset'ul Tap-Socket-7 of which the following is a specification.

This invention relates to tap sockets 'or chucks, and is particularly adapted for use 10 in nut-tapping machines, although it is applicable for variouspurposes, such as chucks for drills, reainers and similar cutiting tools.

The object of this invention is to provide 1.5 an improved socket to he supported from l the spindle of the nut-tapping' machine into which the Shanks of the taps ran he inserted to be securely retainetlftherein and to he revolved with the spindle, and to be raised and lowered'with the spindle, as the spindle' is moved for the purpose of inserting nut-s thereinunder.

Another obj-eet is to provide convenient and yimproved means for removing or insertingg` a tap from the socket either while the spindle and socket are revolving; or while they are at a standstill, it being necessary at times to remove or insert the tap `while the spindle is revolving.

A further object is to provide means tor automatically ejeeting the tap on the same becoming filled with tapped nuts which are allowed to gather thereon by a careless oper- `ator of the machine. 4

To the above ends this invention is ernv bodied essentiallyv in a binding ring contained within the socket, through which the shank of the tap ispassed upon its being: inserted into the socket, which binds the tap in position to prevent the removal thereof,

and a slidable sleeve or bushing arranged between the socket and the tap which can be moved to release the said ring'to nllo\v the tap to he removed from the socket.

The invention is more fully set forth in the following description, it, being upde'rstood, however that the particularconstruetion of the details may 'be 'altered within.

the scope of the appended claims without ,50 departing from the' spirit of the invention.

This invention is illustrated in the aeoompanying drawi lgs, in which similar reference characters indicate similar parts, and

parts broken away.

` In the drawings, the nut-tapping machine carrying the revolvlng spmdle or spindles l as been omitted,` these machines being con;h

mon and theapplieation of this socket thereto being obvious, and for the further reason that this socket may heapplied to various other machines and no special ma chine is essential to its operation.

l'leterring speeilirally tothe drawings, 5?

'indicates a'. cylindrical shell having: its

upper end open and internally'. screw threaded and 1n the lower end thereof a here or passage 11 therethrough. Into the` said screw-threaded end of the shell is engaged the externally screw-threaded head 6 having an upstanding tapered shank 5. This shank is adapted to be engaged into the depending spindle of the nut-tapping machine (not shown) and therefore Carries withit, as it is revolved hy the spindle, the shell 9. lVithin the bore 11 slidably lits a bushing or sleeve 1() having the upper flange 12 within the end of the shell 9 vand normally restingy on the end of the shell', and the lower end thereof protrudes below the end of 'said Shell. The shank 13, which is Vot the'straight shank type` o the tap, drill or reainer is passed through the bushing 1G, which bushing serves to Center the same. The shank lil has a flattened end 14 which enters the slot 7 in the head 6 thereby causing the shank 13 to revolve with the spindle. Within the cylindrical shell9is arranged a binding-ring 15 the hole Cf which ot slightly larger diameter than the shank 13. A lug or stud 17 projects into theshell 9 from one side thereof and the .ring 15 being' arranged above the same rests 'thereon toisupport one side thereof. and the other side of the same being unsupported falls or drops downward due to the weight thereof. A spirallyroiled spring 1G has its smaller and upper end eno'aging over the hess 8 on the lower end of the. head (i'andlho lower endof the saine pressing` against the upper face of the ring l5 at its periphery to 0X- pedite the fall of he 'unsupported side thereof.

Ln use, the shank 13 being passed through the bushing 1() passes through the ring 15, the flattened end 14 thereof engaging the slot 7 of the head 6, and the ring 15 binds the shank against outward movement.

Then by pushing the'bushing 10 upward the ring 15 is brought to a horizontal position and the shank lil is'ree to drop ont or 'be removed. ln a nut-tapping machine it is frequent that due to carelessness on the part of the operator 'thereof the tapped nuts are allowed to lill the shank 13, and if this is the ease when this socket is used, the bushing 1() will be automatically raised by the nuts, being pushed upward on the shank 13 and the shank will be ejeeted or released. The objects aimed at, therefore, are etlieiently attained in the above manner.

In the form shown in Fig. 8 the lug or 'stud 17 is replaced by a small coiled Wire` spring 17 which seats at its lower end in the recess 18 in the bottom of the casing 9 and works in a vertical groove 19 in the said easing to resiliently support the binding ring at one side, thus allowing the shank 13 to b Withdrawn Without, raising the bushing 10 if sufficient force is applied to the shank. This is of at vantage for the reason that the shank may be released by drawing the. same outwardagainst the tension ot' the spring 17', particularly when it is not practical er possible to move the bushing 10 inwardly, and the shank 13 in being drawn outwardly pulls ythe binding ring therewith, which causes the binding ring to strike the inner end of the bushing and thereby bring the binding ring in a horizontal. position to free the shank. The shank may therefore be disengaged by manually drawing the same outwardly, either when at a stand stillor 'when rotating, or the shank may be automatically released by the Weight of the nuts accumulating thereon, when the Weight of the nuts is suflieient to overcome the tension of the spring 17", will he understood.

llaving described the invention what is claimed as new is 1. A tap, drill or reamer socket comprising a shell, shank engaging means at the upper end thereof, a binding ring in the shell below the said means, and means for supporting-the binding ring at one side s0 that a shank is insertible through the binding ring to be supported thereby and is arranged to be engaged by the shank engaging means to rotate therewith.

2. A tap, drill or reame-.r socket embodying a shell, shank engaging means at the upper end thereof, a binding ring Within the shell below the said means, means tor-supporting the binding ring at one side, and a bushing slidable in the lower end of the shell and adapted to strike the binding ring, sothat a shank is insertible through the bushing and through'the binding ring to be supported thereby. and is arranged to be gngaged by the shank engaging means to rotate therewith. 1

3. A tap, drill or reamer socket, conujnising a shell, shank engaging means at. tho upper end thereof, binding ring in the shell below the said means, means for supporting the binding ring at one side, and a coiled spring pressing against the upper iace of the binding ring, so that a shank is insertible through the binding ring to he supported thereby and is arranged to be engaged by the shank engaging means to rotate therewith.
